The 120-lb force P is applied to the 240-lb crate, which is stationary before the force is applied. Determine the magnitude and direction of the friction force F exerted by the horizontal surface on the crate. The friction force is positive if to the right, negative if to the left. Assume u s = 0.48, u k = 0.37. P Answer: F= i lb
